Higher-order spin noise statistics

New Journal of Physics, 2013
The optical spin noise spectroscopy (SNS) is a minimally invasive route toward obtaining dynamical information about electrons and atomic gases by measuring mesoscopic time-dependent spin fluctuations. Recent improvements of the sensitivity of SNS should

Modified Mann-Kendall with higher-order statistics for trend analysis [PDF]

Scientific Reports
Trend analysis of rainfall events is important to understand changes in precipitation patterns over time, which may affect climate adaptation planning. The Mann–Kendall (MK) trend test is preferred by researchers for its robustness in handling non-normal

Motion estimation using higher order statistics [PDF]

IEEE Transactions on Image Processing, 1996
The objective of this paper is to introduce a fourth-order cost function of the displaced frame difference (DFD) capable of estimating motion even for small regions or blocks. Using higher than second-order statistics is appropriate in case the image sequence is severely corrupted by additive Gaussian noise.
